Anyone else using the iScroll2 two finger scrolling drivers available for the older powerbooks and ibooks?

Been using them about a week, instead of sidetrack and they seem to be work quite well, I originaly tried the version that allowed all scrolling options but that seemed a bit buggy still as I was getting jumping in some places so I've gone back to the X and Y scrolling only.

Just wondered what everyone else thought and if they had caused anybody else any problems?
I break stuff.
